Description
- The present invention relates to a male contact formed by bending a sheet of metallic plate.
- There is well known, as shown in
Fig. 10 to Fig. 14 , a male contact having a mating section for mating with a female contact on one end of a base and a wire connecting section on another end of the base, the male contact being formed by punching processing and bending processing of a sheet of metallic plate. -
Fig. 10 is a sectional view of a mating section of the conventional male contact taken along the direction perpendicular to the mating direction (cf. JapaneseToku-Kai-Hei 8 - 162191 mating section 10a is formed in such a manner that bothedge portions plate member 50a represented by a broken line are folded (cf. arrows a), so that both theedge portions plate member 50a. -
Fig. 11 is a sectional view of a mating section of another conventional male contact taken along the direction perpendicular to the mating direction (cf. JapaneseToku-Kai-Hei 7 - 192793 mating section 10b is formed in such a manner that bothedge portions plate member 50b represented by a broken line are wound (cf. arrows b), so that both theedge portions mating section 10b is different from themating section 10a formed by folding of both the edge portions as shown inFig. 10 , and is provided withcavity sections mating section 10b by winding. -
Fig. 12 is a sectional view of a mating section of further another conventional male contact taken along the direction perpendicular to the mating direction (cf. JapaneseToku-Kai-Hei 8 - 162191 mating section 10c is formed in such a manner that a sheet ofplate member 50c represented by a broken line is folded taking as a crease the center axis extending in the mating direction of theplate member 50c (cf. an arrow c), so that both edge portions of theplate member 50c are confronted with one another at one end of theplate member 50c and thereby forming acavity 52c. -
Fig. 13 is a perspective view showing a state of a mating section of the conventional another male contact before the folding processing (cf. JapaneseToku-Kai-Hei 9 - 147947 base 20d is formed in such a manner that a sheet ofplate member 50d having a length twice the mating section extending along the mating direction is folded at theintermediate section 53d in a longitudinal direction of the plate member, which will be the top of the mating section, toward the side of thebase 20d (cf. an arrow d). -
Fig. 14 shows another male contact disclosed by the above-mentioned Japanese Patent Publication Gazette. Part (a) ofFig. 14 is a perspective view showing a state of the mating section before bending processing of the mating section of the male contact. Part (b) ofFig. 14 is a perspective view showing a state of the mating section after the bending processing of the mating section of the male contact. Amating section 10e shown in the part (b) ofFig. 14 is formed by performing the bending processing for a sheet ofplate member 50e shown in the part (a) ofFig. 14 . The bending processing is performed in such a manner that bothedge portions top portion 54d of aplate member 50e, are folded (cf. arrows e1), and both theedge portions plate member 50e, and the edge side of thetop portion 54d of the plate member is folded to the base side not illustrated (cf. an arrow e2). - Higher density of loading electric components needs compactness of male contacts. However, it is difficult to implement the compactness of mating sections having the conventional aspects as shown in
Fig. 10 to Fig 14 with a plate member having a plate thickness satisfying a desired strength. Specifically, in the event that themating section 10a formed by folding of both the edges as shown inFig. 10 is formed using a plate member having a plate thickness satisfying a desired strength, the narrower width w (cf.Fig 10 ) of the mating section, it is more difficult to perform folding both the edges. Even if processing for the folding of both the edges is carried out, a section of the mating section is easy to be a circle in its shape. This will cause a contact area with an elastic contact segment of the female contact to be small, and thus there is a possibility that a reliability of the electric contact is lowered. Further, themating section 10b formed by winding of both edge portions as shown inFig. 11 has no flat portion on the top thereof, so that a contact area with an elastic contact segment of the female contact is small, and thus it is difficult to enhance a reliability of the electric contact. In the event that themating section 10c formed by folding taking the center axis as a crease as shown inFig. 12 is formed using a plate member having a plate thickness satisfying a desired strength, the narrower width w of the mating section, the more arc-like shape the folding side is concerned with. This will cause a contact area with an elastic contact segment of the female contact to be small, and thus it is difficult to enhance a reliability of the electric contact. In the event that the mating section formed by bending processing by folding to the base side as shown inFig. 13 needs a plate member having twice length of the mating section extending along the mating direction. This involves a basic problem that the production efficiency is not so good and a yield rate of the materials is low, while the contact area is secured. Themating section 10e formed by folding of three points as shown inFig. 14 is associated with a possibility that an elastic contact segment of the female contact is damaged by a seam on an upper surface of the mating section, as well as the basic problem that the production efficiency is inefficient. -
WO 93/15532 - In view of the foregoing, it is an object of the present invention to provide a male contact solving the above-mentioned problem, or a male contact which is high in reliability of an electric contact with the female contact and has a mating section capable of being formed with a compactness using a plate member having a plate thickness satisfying a desired strength.
- The present invention provides a male contact formed by folding a sheet of metallic plate, said male contact comprising a base and a mating section adapted to mate with a female contact, wherein said mating section is formed in such a manner that two sheets of plate members, which individually extend from said base, are superposed on one another, said two sheets of plate members superposed on one another have each a flat section extending in a mating direction and formed flat on an associated outer surface opposite to surfaces on which said two sheets of plate members are in contact with one another, characterized in that said two sheets of plate members are superposed on one another by folding on said base; and a tip of one of said two sheets of plate members is folded to overlap a tip of another.
- In the male contact according to the present invention as mentioned above, it is preferable that said mating section has a projecting section on one of said two sheets of plate members superposed on one another, said projecting section projecting toward another plate member, and a recess portion adapted to mate said projecting section with said another plate member.

Themale contact 1 is provided with amating section 10 at one end of abase 20, and awire connecting section 30 at another end of thebase 20. A plurality ofmale contacts 1 is coupled with acarrier 40 at another end of thewire connecting section 30, and is separated from thecarrier 40 when themale contacts 1 are actually used. Thewire connecting section 30 electrically connects wires (not illustrated). Themating section 10 mates with a female contact (not illustrated) in an mating direction P to electrically connect with an elastic contact section (not illustrated) of the female contact. Themating section 10 has two sheets ofplate members base 20. Those two sheets ofplate members mating section 10 is formed in such a manner that those two sheets ofplate members mating section 10, which is the narrowest part of the parts of themale contact 1, is about a little longer than twice the plate thickness (0.25 mm in the present embodiment) of the plate member. Thus, it is possible to implement a compactness of the mating section using the plate member having a plate thickness satisfying a desired strength, and also it is easy in processing. A plurality ofmale contacts 1 is fixed on an insulating housing (not illustrated) and is used as an electrical connector. - Hereinafter, there will be explained the

Accordingly, the male contact is high in reliability of the electric contact with the female contact. Incidentally, according to the preferred embodiment, a cross sectional size of themating section 10 is 0.64 mm x 0.64 mm, and width of theflat section 15 is secured with about 0.3 mm. - As shown in
Fig. 2 , atip 13 of theplate member 12 of the lower side is folded to overlap on atip 14 of theplate member 11 of the upper side. This folding makes it possible to fix theplate members plate members tip 13 of theplate member 12 of the lower side is simply folded on thetip 14 of theplate member 11 of the upper side, thickness of this folding section would become about 0.75 mm. For this reason, as apparent fromFig. 9 , thetips plate members thinner sections tips plate members plate members tips Fig. 3 , and thetip 13 of theplate member 12 of the lower side is obliquely folded to the side of theplate member 11 of the upper side and thetip 14 of theplate member 11 of the upper side is obliquely folded to the side of theplate member 12 of the lower side, so that the tip of one of theplate members - As shown in
Fig. 8 andFig. 9 , in the vicinity of the center of theplate member 12 of the lower side of theplate members mating section 10. there is provided a projectingportion 16 projecting toward theplate member 11 of the upper side.

Theinsulation barrel 31 and thewire barrel 32 apply the covering section and the core wire respectively by a folding processing. - Incidentally, according to the present embodiment, the thinner plate thickness of the
plate members male contact 1 becomes easier. Thus, themale contact 1 is fabricated with a metallic material having the lowest plate thickness satisfying a desired strength as a result of a strength computation. On the other hand, width and height of the mating section are defined by a standard and the like. According to the present embodiment, in order to provide the lowest plate thickness satisfying a desired strength for a plate thickness of the plate member and also satisfy conditions of width and height of the mating section defined, as shown inFig. 7 , there are providedlegs Fig. 1 ) of the twoplate members flat sections legs 18, are slants necessarily formed for forming themating section 10 having thickness 0.64 mm using two plate members each having the plate thickness 0.25 mm according to the present embodiment. Slants 18_1, 18_1, 18_1 and 18_1 also function as planing off the corners of the edge portions extending along the mating direction P of themating section 10. This feature makes it possible to prevent the female contact from being damaged at the time of mating. Further, as thelegs cavity 19 is formed in the vicinity of the center axis of themating section 10 extending the mating direction P so that the same effect as forming of beads on theplate members mating section 10. - While the above explanation is made for the preferred embodiment of the present invention, the present invention is not restricted to the present embodiment, and can be modified within the scope of the claims.
- For example, it is acceptable that the tip of the
plate member 11 of the upper side is folded on the tip of theplate member 12 of the lower side. Alternatively, it is acceptable that theplate member 11 of the upper side is provided with a projecting portion projecting toward theplate member 12 of the lower side, and theplate member 12 of the lower side is provided with a recess portion mating with the projecting portion. - According to the male contact disclosed in
claim 1, in the male contact formed by folding a sheet of metallic plate, said male contact comprising a base and a mating section adapted to mate with a female contact, said mating section is formed in such a manner that two sheets of plate members, which individually extend from said base, are superposed on one another by folding on said base; said two sheets of plate members superposed on one another have each a flat section extending in an mating direction and formed flat on an associated outer surface opposite to surfaces on which said two sheets of plate members are in contact with one another; and a tip of one of said two sheets of plate members is folded to overlap a tip of another. This feature makes it possible to provide a male contact which is high in reliability of an electric contact with the female contact and has a mating section capable of being formed with a compactness using a plate member having a plate thickness satisfying a desired strength, wherein the tips of the two sheets of plate members are hard to open. - Further, according to the male contact disclosed in claim 2, said mating section has a projecting section on one of said two sheets of plate members superposed on one another, said projecting section projecting toward another plate member, and a recess portion adapted to mate said projecting section with said another plate member. This feature makes it possible to prevent the mutual deviation of the two sheets of plate members in a horizontal direction perpendicular to the mating direction.
